NSAlert beeping

I've got a situation where an alert, attached as a sheet, just beeps 
when it's called (instead of displaying and interacting with the 
user.)  I'm about 99.99% certain that this is being caused by a sheet 
that comes up prior to the alert (not at the same time -- the previous 
sheet is long gone, theoretically, from the window when this alert is 
called.)

Weird thing is that the exact same code in a different class works a-
ok, so I'm a little mystified, but knowing why an alert would just 
beep, rather than come up, would be a great start.  The previous sheet 
is a progress metre, which comes up and goes away without any user 
involvement.  If I call the progress metre twice, there's another beep 
and the panel is displayed detached from the window.

The "endpanel" function, which does get called, contains nothing more 
than an orderOut:nil.  Adding a close call neither helps nor hinders.

So, what have I done to my window with this first sheet which causes 
subsequent alerts to beep instead of displaying?

Thanks!
